Shadow Step (Recharge 4–6) As a bonus action, Bes teleports up to 60 feet to an unoccupied space he can see that is in dim light or darkness. After teleporting, Bes has advantage on the first melee attack he makes before the end of his turn.   Blood Frenzy Bes has advantage on melee attack rolls against any creature that doesn’t have all its hit points. While in Blood Frenzy, Bes must use his full movement and all actions each turn to move toward and attack the nearest creature. He can’t willingly retreat or take the Disengage action.   Primal Ferocity When Bes drops below half his hit points for the first time, he enters a frenzied state for 1 minute. During this time, he gains resistance to bludgeoning, piercing, and slashing damage from nonmagical attacks, makes one additional claw attack whenever he takes the Attack action, and automatically fails Wisdom saving throws against being charmed or frightened.   Shadow Plane Escape (1/Day) As an action, Bes steps through the veil between worlds, vanishing into the Shadowfell or the Plane of Shadow. While there, he can remain for up to 1 hour or until he chooses to return to his original plane, reappearing in a space of dim light or darkness within 1 mile of where he vanished.   Actions Multiattack Bes makes three attacks: one with his Bite and two with his Claws.   Bite Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 18 (2d10 + 6) piercing damage.   Claw Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 6) slashing damage.   Pounce If Bes moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 18 Strength saving throw or be knocked prone. If the target is prone, Bes can make one bite attack against it as a bonus action.   Shadow Blur (1/Turn) When a creature Bes can see targets him with an attack and he is in dim light or darkness, Bes imposes disadvantage on the attack roll.   Malar’s Spite When Bes is subject to a critical hit he may react with a claw attack to the creature that inflicted it. Creatures hit but this claw attack must make a DC 16 wisdom saving throw or be cursed. Malar’s Spite prevents natural healing untill the curse is lifted with a remove curse spell of atleast 5th level.
